(CNN)–Famed TV scientist Bill Nye is slamming creationism in a new online video for Big Think titled “Creationism Is Not Appropriate For Children.”

“Denial of evolution is unique to the United States,” Nye begins in a YouTube video posted on Thursday. The video quickly picked up steam over the weekend and as of Monday morning had been viewed more than 1,100,000 times.

Nye — a mechanical engineer and television personality best known for his program, “Bill Nye the Science Guy” — said the United States has great capital in scientific knowledge and “when you have a portion of the population that doesn’t believe in it, it holds everyone back.”

“Your world becomes fantastically complicated if you don’t believe in evolution,” Nye said in the Web video.
